From the Splash Pad at LeFrak to the Water Lab at Brooklyn Bridge Park, there is no shortage of water play for Brooklyn kids. But what about real-deal swimming pools? We’ve got those, too! Fifteen of them, in fact. New York City’s outdoor pools are officially open for business. Conveniently, they all keep the same hours, so it’s easy to remember: seven days a week, 11:00 a.m. through 7:00 p.m., with a break for pool cleaning between 3:00 p.m. and 4:00 p.m. Nothing tires out toddlers like swimming. Get out there and play.
